You will have to patch /stats/effects/food/wellfed/wellfed.statuseffect . Your patch would look something like: Code: [ {"op": "replace", "path": "/defaultDuration", "value": 120 } ] ...which would set the duration to default and not really do anything -- but you can change that 120 to the number of seconds you like. (Don't rename the path, of course: even if you're changing the value, what you're changing it to becomes the new default.) That file would be /Starbound/yourmodname/stats/effects/food/wellfed/wellfed.statuseffect.patch .
